Frustrations

I have a lot to finish up at work before taking off for vacation so I am "running" at a even higher speed than normal. So instead of being effective, I am actually not getting any cooperation from others which is SO FRUSTRATING!! I can't help but wonder what is going on with everyone? Thanks to a coworker who is like a 先輩 to me and gave me an analysis on the whole situation. Basically, I have everything thought out and laid down in my head and pretty much have the ideas of what to do and the direction to take, so when I present them at the meetings, I go so fast with all the information that I am not giving people a chance to think it over. They might feel I am forcing it down their throats, despite it being a good or right direction. So all I get are endless questions of "Why....?" and "What is the point ...?" and basically an automatic "No". I need to learn to deliver my message at a slower pace. I might even want to learn to throw in a few jokes to lighten up the meetings. Not everyone is as tuned in or as clear about the issues as me, so I need to learn to accommodate everyone by giving them time to understand the issue and the proposal and gradually a buy-in to the idea. I can not expect a "Yes, madam!" at the meeting especially when there are managers from other functional groups present.
Now I understand why I give others an aggressive impression, when all I want is to get things done and cross out from my "to close" list. All my thinking and preparation will go to waste when I don't let people warm up to it. I need to remember to lower my RPM for fuel efficiency.
